Estrogen is an important sex hormone for women. As a steroid hormone, it diffuses across cell membranes, delivering messages and helping regulate sexual function, fertility, and body weight. There are three forms of estrogen that circulate through the body, estrone, estradiol, and estriol. Estrogen levels change naturally over time, and those levels can create drastic changes. Our test checks the levels of estradiol, the primary form of estrogen found in the body. If your estrogen is out of balance you may suffer from irritability, drastic mood changes, hot flashes, and weight gain. Testing your estrogen levels with a simple at-home saliva sample can provide valuable insight into your estradiol levels, enabling you to take charge of your health.
